Definitions

  • the display apparatus converts a format of the input image into a displayable format by adjusting a resolution and the like of the image.
  • the display apparatus adjusts the resolution and size of the image according to its inherent resolution.
  • an aspect ratio of the input image is not equal to an aspect ratio of the display apparatus, the image can be reduced or enlarged in a particular direction, which may result in distortion of the original image.
  • small-sized display apparatuses such as portable display apparatuses, electronic frames and so on, which have recently been in active use, have a limitation in displaying and storing images having a resolution higher than those of the display apparatuses due to a restriction on a storage space.
  • Another aspect of the present invention is to provide a display apparatus and a control method of the same, which are capable of reducing a storage capacity required to store an image.
  • Still another aspect of the present invention is to provide a display apparatus and a control method of the same, which are capable of processing and displaying an image without difficulty.
  • a display apparatus including a display unit, including: an image processing unit; an image receiving unit which receives an image from an image source; and a controller which controls the image processing unit to crop the received image to a reference aspect ratio and scale the cropped image according to a resolution of the display unit.
  • the image processing unit may crop a width of the received image if the received image is a widthwise image and may crop a length of the received image if the received image is a lengthwise image.
  • the image processing unit may crop a left portion and a right portion of the received image at an equal first ratio if the width of the widthwise image is cropped and may crop an upper portion and a lower portion of the received image at an equal second ratio if the length of the lengthwise image is cropped.
  • the display apparatus may further include a user interface generating unit which superimposes a frame having the reference aspect ratio on the received image and moves the frame according to an input from a user.
  • the display apparatus may further include a storing unit, and, when the image is received from the image source, the controller may control the image processing unit to crop the received image and may store the cropped image in the storing unit.
  • the reference aspect ratio may be an aspect ratio of the display unit.
  • the received image may include a still image.
  • a display apparatus and a control method of the same which are capable of reducing a storage capacity required to store an image.
  • FIG. 1 is a control block diagram of a display apparatus according to an exemplary embodiment of the invention
  • FIG. 3 is a control block diagram of a display apparatus according to another exemplary embodiment of the invention.
  • FIG. 4 is a view for explaining an image processing method of the display apparatus shown in FIG. 3 according to an exemplary embodiment of the invention
  • the image receiving unit 10 may include a connector to which a storage medium such as a USB memory, a camera within which photographs are stored, etc. may be connected, an interface which may be connected to a network, and/or a broadcasting receiving unit which may receive a broadcasting signal.
  • the image receiving unit 10 may be implemented by Bluetooth, an infrared communication interface and wired/wireless USB communication interface or the like.
  • An image received in the image receiving unit 10 has an aspect ratio which is commonly called “picture ratio.”
  • a camera provides various picture ratios of 4:3, 16:9, 6:6 and the like to generate images having various aspect ratios.
  • the display unit 20 displays the image processed in the image processing unit 30 .
  • the display unit 20 may include a display panel such as a liquid crystal display (LCD) panel which contains liquid crystal elements, an organic light emitting diode (OLED) panel which contains organic light emitting elements, or a plasma display panel (PDP), and a panel driver which drives the display panel.
  • the display unit 20 has typically a rectangular shape whose aspect ratio (ratio of length to width) may include 16:9, 4:3 or the like. Since such an aspect ratio is determined in a manufacture stage, if an aspect ratio of the input image is not equal to an aspect of the display unit 20 , a distortion may occur in the image.
  • FIG. 2B is a view for explaining a method of processing a widthwise image with its width longer than its length (having an aspect ratio of 16:9). If the aspect ratio of the display unit 20 is 4:3, the image processing unit 30 removes width (C 1 and C 2 ) of the image by 30% or so such that the aspect ratio of the image corresponds to the aspect ratio of the display unit 20 . In this case, the left and right portions of the image may be cropped at the same ratio (15%). An aspect ratio of the image with its width cropped becomes 4:3 which is equal to the aspect ratio of the display unit 20 .
  • the preset aspect ratio corresponds to the aspect ratio of the display unit 20 .
  • the controller 50 automatically compares the aspect ratio of the image with the aspect ratio of the display unit 20 . Thereafter, if it is determined that the aspect ratio of the image is different from the aspect ratio of the display unit 20 , the controller 50 controls the image processing unit 30 to adjust the aspect ratio of the image.
  • a small-sized display apparatus may have high limitation on its storage space. For the purpose of alleviating such limitation, the controller 50 may adjust the aspect ratio of the image while receiving the image and store the image with the adjusted aspect ratio in the storing unit 40 .
  • FIG. 3 is a control block diagram of a display apparatus according to another exemplary embodiment of the invention. As shown, the display apparatus according to this exemplary embodiment further includes a user selecting unit 60 and a UI generating unit 70 .
  • the user selecting unit 60 corresponds to a user interface for selecting a particular portion of a cropped image.
  • the user selecting unit 60 may include an input device such as a keyboard, a mouse, buttons, a remote controller or the like and preferably includes a touch panel connected to the display unit 20 .
  • the touch panel may be disposed in front of the display unit 20 or may be built in the display unit 20 and may include various configurations for sensing pressure by a user's finger or a point device.
  • the UI generating unit 70 generates various graphic interfaces to allow a user to select a portion to be cropped in the image and displays the generated graphic interfaces on the display unit 20 .
  • FIGS. 4 to 6 are views for explaining a method of adjusting an aspect ratio of the image in correspondence to the various graphic interfaces and a user's input. In these figures, shaded portions indicate the cropped images.
  • FIG. 4 shows that a user selects an image displayed or stored where the user selecting unit 60 is provided as a touch panel.
  • the received image is first displayed on the display unit 20 and may be partitioned into a plurality of regions ( ⁇ circle around ( 1 ) ⁇ , ⁇ circle around ( 2 ) ⁇ and ⁇ circle around ( 3 ) ⁇ ).
  • the user may select a region the user desires to keep and the image processing unit 30 adjusts an aspect ratio based on the selected region.
  • the first and second regions ( ⁇ circle around ( 1 ) ⁇ and ⁇ circle around ( 2 ) ⁇ ) except the third region ( ⁇ circle around ( 3 ) ⁇ ) are mostly cropped.
  • the width of the display unit 20 is longer than the length thereof as shown in FIG. 2C , the lengthwise image is cropped such much that the original image is put into the shade. In this case, since upper and lower portions of the image are automatically cropped at an equal ratio, there exists a possibility that an important portion of the image is cropped. This exemplary embodiment is provided to make up for such a defect, in which a user can select an image desired to be kept.
  • the UI generating unit 70 generates a user interface (UI) for indicating dotted lines or regions to partition the image and displays the generated UI on the display unit 20 .
  • the number of regions to partition the image may be set or changed by means of the user selecting unit 60 .
  • FIG. 5 shows that a user partially selects an image to be deleted. As shown, dotted lines to define a plurality of regions are indicated on the image and a user can select any region to be cropped.
  • This exemplary embodiment is the same as the exemplary embodiment of FIG. 4 in that the user can select an image to be kept, but is different from the exemplary embodiment of FIG. 4 in that images to be cropped are discontinuous. According to the exemplary embodiment of FIG. 5 , the user can more partially select an image desired to be cropped.
  • a reference aspect ratio is applied to an image adjusted by the user, a portion that the user can select is limited by the reference aspect ratio, and accordingly the user can not select a portion that would deviate away from the reference aspect ratio.
  • the controller 50 controls the image processing unit 30 to display an image from which a portion selected by the user is deleted. That is, a preview function may be provided. If the user is not satisfied with the image with the adjusted aspect ratio, the user would again select a portion to be deleted from the original image.
  • a frame P with a reference aspect ratio is overlapped with an image.
  • a user may move, enlarge or reduce the frame P and more precisely adjust an image to be selected.
  • An internal region of the frame P is stored in the storing unit 40 or is displayed on the display unit 20 and an external region of the frame P is cropped.
  • the user selecting unit 60 facilitates a fine adjustment, thereby allowing the user to select a desired image with most ease and precision.
  • an image with its aspect ratio not adjusted may be stored in the storing unit 40 .
  • the user may display an image through the user selecting unit 60 and then select a particular portion, which is desired to be stored, of the image, and the image processing unit 30 may crop the image correspondingly.
  • An image with its aspect ratio adjusted may be stored along with or in place of an existing image.
  • the reference aspect ratio may be set by a user without being fixed to the aspect ratio of the display unit 20 . If the user sets a desired aspect ratio in consideration of characteristic and resolution of a received image, the user can freely edit the image, which may lead to user's high access to and high intimacy with the display apparatus.
  • FIG. 7 is a control flow chart for explaining a control method of the display apparatus shown in FIG. 3 .
  • An image processing method of the display apparatus of the present invention will be described with reference to FIG. 7 .
  • the controller 50 determines whether or not an aspect ratio of the image is equal to a reference aspect ratio (S 20 ).
  • the reference aspect ratio may be set to be an aspect ratio of the display unit 20 and may be altered by a user.
  • the controller 50 controls the UI generating unit 70 to provide the user with various graphic interfaces to allow the user to select a particular portion of the image to be cropped.
  • the user uses the user selecting unit 60 to select an image to be cropped or an image to be conserved (S 30 ).
  • width of a widthwise image will be cropped at an equal ratio or length of a lengthwise image will be cropped at an equal ratio.
  • the image processing unit 30 crops the image such that the aspect ratio of the image becomes the reference aspect ratio (S 40 ) and stores the image with the adjusted aspect ratio in the storing unit or scales the image for display on the display unit 20 (S 50 ).
  • the image may be stored and displayed at the same time.
